Key Parameters

Substitute Part Grouping Explanation

Substitution of the HIF3B-26PA-2.54DS(71) is determined by strict equivalence across the following critical parameters:

• Connector Series & Type: Both parts must belong to the HIF3B series and function as headers with male pin contacts
• Position Count & Row Configuration: 26 positions in 2-row arrangement is mandatory
• Pitch Specifications: Mating pitch and row spacing must both be 0.100" (2.54mm)
• Mounting & Orientation: Through-hole, right-angle mounting configuration required
• Shrouding & Fastening: Shrouded 4-wall construction with latch lock/eject hooks required
• Electrical Ratings: Voltage rating of 200V and contact material (brass with gold mating finish and tin post finish) must be maintained
• Material & Compliance: PBT insulation, UL94 V-0 flammability rating, and RoHS compliance required

The HIF3B-26PA-2.54DS(63) qualifies as a direct substitute based on these parameters. The primary distinction is product status: the substitute part is active, whereas the main part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The HIF3B-26PA-2.54DS(63) is the direct equivalent substitute for the obsolete HIF3B-26PA-2.54DS(71). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The substitute part carries active product status from Hirose Electric Co Ltd, ensuring ongoing availability and supply chain continuity.

Both parts satisfy RoHS compliance requirements and carry UL94 V-0 flammability certification, meeting regulatory and safety standards for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part.

The substitute part is supplied in tray packaging, which may differ from the original part's packaging specification. This distinction is relevant only for procurement and handling procedures and does not affect functional or electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can HIF3B-26PA-2.54DS(63) be used as a direct replacement for HIF3B-26PA-2.54DS(71)?

A: Yes. Both parts are identical in connector type, position count, pitch spacing, mounting configuration, electrical ratings, and material specifications. The substitute part is functionally and mechanically equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The HIF3B-26PA-2.54DS(71) is obsolete, while the HIF3B-26PA-2.54DS(63) is active. The suffix designation (71 vs. 63) indicates different manufacturing batches or packaging configurations. The substitute part is supplied in tray packaging.

Q: Are there any electrical or thermal differences between these parts?

A: No. Both parts operate at 200V voltage rating, maintain the same -55°C to 85°C temperature range, and use identical contact materials and finishes. Current rating specifications are equivalent.

Q: Will the substitute part fit existing PCB layouts designed for the original part?

A: Yes. Both parts share identical mounting type (through-hole, right-angle), pitch spacing (0.100" / 2.54mm), and row configuration (2 rows, 26 positions). PCB footprints and mechanical mounting are fully compatible.

Q: Are both parts RoHS compliant?

A: Yes. Both the HIF3B-26PA-2.54DS(71) and HIF3B-26PA-2.54DS(63) are RoHS compliant and carry UL94 V-0 flammability certification.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints. Standard handling and storage procedures apply.
