Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Amphenol ICC 87610-214LF

The Amphenol ICC 87610-214LF (Quickie™ series) is an active product that provides direct functional equivalence to the obsolete TE Connectivity 281272-1. This connector maintains all critical mating parameters and is RoHS compliant. The phosphor bronze contact material offers enhanced durability compared to brass. The GXT™ gold finish on mating contacts provides superior corrosion resistance. Material flammability certification (UL94 V-0) is provided. This part is suitable for new designs and production applications requiring an active alternative to the obsolete original.

Secondary Substitute: Assmann WSW AWHW 14G-0202-T

The Assmann WSW AWHW 14G-0202-T provides full mechanical and electrical compatibility with the original connector. This part is active and offers the highest inventory availability (5798 units). It is ROHS3 compliant and REACH unaffected, providing regulatory clarity for international applications. Operating temperature range (-40°C ~ 105°C) and current rating (3A) are explicitly specified. The brass contact material matches the original design. This connector is appropriate for applications requiring maximum supply chain availability and regulatory transparency.

Selection Criteria:

• For durability and corrosion resistance: Select 87610-214LF (Amphenol ICC)
• For supply availability and regulatory clarity: Select AWHW 14G-0202-T (Assmann WSW)
• For cost-optimized procurement: Evaluate both based on current pricing and lead time

All three connectors share identical mating interface geometry, keying slot design, and push-pull fastening mechanism, ensuring direct interchangeability at the board level.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 87610-214LF directly replace the TE Connectivity 281272-1 in existing designs?

A: Yes. Both connectors maintain identical mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), position count (14 in 2 rows), shrouding configuration (4-wall), and fastening mechanism (push-pull). The mating interface is fully compatible. Minor variations in contact length and insulation height fall within acceptable mechanical tolerances for board-level integration.

Q: What is the difference between the contact materials used in these connectors?

A: The TE Connectivity 281272-1 and Assmann WSW AWHW 14G-0202-T use brass contacts, while the Amphenol ICC 87610-214LF uses phosphor bronze. Phosphor bronze provides higher spring force retention and improved durability under repeated mating cycles. Brass offers cost efficiency and adequate performance for standard applications. Both materials are compatible with the gold mating finish and tin post finish specified across all three connectors.

Q: Are there packaging differences between these substitute parts?

A: Yes. The Amphenol ICC 87610-214LF is supplied in tube packaging, while the Assmann WSW AWHW 14G-0202-T is supplied in tray packaging. Tube packaging is suitable for automated assembly processes, while tray packaging is optimized for manual handling and smaller production runs. Select packaging based on your assembly process requirements.

Q: What is the significance of the UL94 V-0 flammability rating on the substitute parts?

A: The UL94 V-0 rating indicates that the insulation material meets stringent flammability requirements, limiting flame propagation and preventing dripping of burning particles. The original TE Connectivity part does not specify a flammability rating. The substitute parts with UL94 V-0 certification provide enhanced safety compliance for applications in regulated industries or environments with flammability concerns.

Q: How do the operating temperature ranges compare?

A: The Assmann WSW AWHW 14G-0202-T specifies an operating temperature range of -40°C to 105°C. The TE Connectivity 281272-1 and Amphenol ICC 87610-214LF do not provide explicit operating temperature specifications. For applications requiring defined thermal performance, the Assmann WSW connector provides documented temperature limits.

Q: What is the difference between REACH Affected and REACH Unaffected status?

A: REACH Affected status (Amphenol ICC 87610-214LF) indicates that the product contains substances subject to REACH regulation and requires compliance documentation. REACH Unaffected status (Assmann WSW AWHW 14G-0202-T) indicates that the product does not contain regulated substances requiring REACH reporting. For applications in European markets or with strict chemical compliance requirements, the REACH Unaffected status simplifies regulatory documentation.

Q: Can these connectors be used interchangeably in the same circuit board design?

A: Yes. All three connectors share identical through-hole mounting footprints, mating interface geometry, and electrical contact configuration. They can be substituted without requiring PCB redesign. Verify that your assembly process accommodates the packaging format of your selected connector (tube or tray).

Q: What is the significance of the contact finish thickness specifications?

A: Contact finish thickness determines durability and corrosion resistance. The TE Connectivity 281272-1 and Amphenol ICC 87610-214LF specify 30.0µin (0.76µm) gold thickness on mating contacts, providing consistent corrosion protection. The Assmann WSW AWHW 14G-0202-T specifies flash gold finish, which is thinner but adequate for standard applications. For high-reliability or harsh environment applications, select connectors with specified finish thickness (30.0µin minimum).

Q: Why is the TE Connectivity 281272-1 classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and no longer supports this part. Active alternatives (87610-214LF and AWHW 14G-0202-T) are recommended for new designs and ongoing production to ensure long-term supply chain stability and manufacturer technical support.
