KA48/254DEFD21TAH Technical Overview: Verified Parameters Before Sourcing
HYPERTRONICS KA48/254DEFD21TAH is a analog signal-chain device cataloged in Analog & Signal Chain, Passives & Connectors (MIL-SPEC) for Aerospace & Defense, Avionics Systems programs. Unlike a family-level listing, the complete ordering code matters: package, temperature grade, speed option, screening level and shipment format can change with a suffix. The structured reference data for this exact part identifies Connector Series KA Series high-reliability rectangular connector, Number of Contacts 48, Contact Pitch 2.54 mm (/254), Row Configuration Four rows (D code).
These values are useful for initial BOM and sourcing review, but engineering approval should still use the latest manufacturer-controlled datasheet, package drawing and change notices. For availability, lot/date code and documentation, send Sparkle Electronics the complete KA48/254DEFD21TAH requirement.

What the Specifications Mean in a Design Review
For this analog signal-chain device, the main compatibility checks are offset, bias current, bandwidth, gain accuracy, noise, supply headroom and output-drive requirements. A replacement should not be approved from the family name alone. The values below need to be checked against the schematic, PCB footprint, power tree, timing constraints, thermal analysis and program qualification baseline:
- Connector Series: KA Series high-reliability rectangular connector
- Number of Contacts: 48
- Contact Pitch: 2.54 mm (/254)
- Row Configuration: Four rows (D code)
- Connector Half: Receptacle (E code)
- Contact Gender: Female socket (F code)
- Termination: Straight PCB dip-solder (D code)
Minimum and maximum values are not interchangeable with typical test values, and package-level compatibility does not guarantee pin, timing or firmware compatibility. Where the assembly is used in high-reliability equipment, confirm the required screening, traceability, lead finish and environmental documentation before purchase.
KA48/254DEFD21TAH and Related HYPERTRONICS Devices
The following pages provide useful internal comparison points. They are related sourcing options, not automatically drop-in replacements:
- ACTEL A1020B-PG84B — compare the exact architecture, package, speed or grade before substitution.
- ACTEL A2F500M3G-1CSG288I — compare the exact architecture, package, speed or grade before substitution.
- ACTEL A2F500M3G-FGG484I — compare the exact architecture, package, speed or grade before substitution.
- ACTEL A3P1000-1FGG484I — compare the exact architecture, package, speed or grade before substitution.
When comparing these devices, start with the exact function and architecture, then verify package and pinout, voltage rails, speed or bandwidth, operating temperature and qualification grade. If any of those differ, an engineering redesign or requalification may be required.
Package, Temperature and Ordering-Code Checks
The orderable code KA48/254DEFD21TAH must be kept intact on the RFQ. Confirm the manufacturer marking, package drawing, terminal finish, moisture handling, operating-temperature requirement and packing format. For obsolete or long-stored material, define acceptable date codes and inspection criteria before quotation rather than after delivery.
Sourcing teams should also request the documentation appropriate to the program: Certificate of Conformance, packing and label photographs, lot/date-code information, traceability, visual inspection, X-ray or electrical testing when required. See our quality-control approach and the broader Analog & Signal Chain, Passives & Connectors (MIL-SPEC) selection.
Applications and Procurement Context
KA48/254DEFD21TAH may be evaluated for Aerospace & Defense, Avionics Systems systems where its verified electrical limits, package and temperature range match the approved design. Typical work includes new production, repair, lifecycle extension and last-time-buy planning. Application labels describe catalog relevance; final suitability remains a system-level engineering decision.
