Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 114281 is determined by strict alignment of the following critical parameters:

Position and Pitch Compatibility: The substitute part must maintain 200 positions at 0.079" (2.00mm) pitch with 8 rows to ensure mechanical and electrical compatibility with existing PCB layouts and mating connectors.

Connector Configuration: The substitute must be a receptacle with female sockets, maintaining the DE 25 connector style classification.

Mounting and Termination: Through-hole, right-angle mounting with press-fit termination is required to match the original installation method and PCB integration approach.

Environmental and Compliance Requirements: The substitute must support the operating temperature range of -55°C to 125°C and maintain equivalent RoHS and REACH compliance status.

Contact System: Gold-plated contacts are required to maintain electrical performance and reliability characteristics.

The TE Connectivity AMP Connectors part number 5646728-1 satisfies all substitution criteria within these parameters.

Both components operate across the identical temperature range of -55°C to 125°C.

Enhanced Specifications: The 5646728-1 provides additional electrical performance data including 1.5 A current rating and 750Vrms voltage rating, along with specified contact finish thickness of 30.0µin (0.76µm). The inclusion of upper shield features in the Z-PACK series provides enhanced electromagnetic performance.

Supply Availability: Current inventory of 660 units for the 5646728-1 supports immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity AMP 5646728-1 be used as a direct replacement for the TE Connectivity Erni 114281?

A: Yes. Both connectors share identical position count (200), pitch (2.00mm), row configuration (8), mounting style (through-hole right-angle), termination method (press-fit), contact finish (gold), and operating temperature range (-55°C to 125°C). The 5646728-1 is the manufacturer-recommended substitute for the obsolete 114281.

Q: What is the difference between the mounting descriptions for these two parts?

A: The 114281 is specified as "Through Hole, Right Angle" while the 5646728-1 is specified as "Board Edge, Through Hole, Right Angle." Both configurations utilize through-hole mounting with right-angle orientation. The board edge designation for the 5646728-1 indicates the connector is designed for edge-mounted PCB applications, which is compatible with standard through-hole installation methods.

Q: Are there compliance differences between the 114281 and 5646728-1?

A: Both components maintain equivalent compliance status. The 114281 is ROHS3 Compliant while the 5646728-1 is RoHS Compliant. Both carry MSL 1 (Unlimited) ratings and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The compliance difference reflects manufacturing timeline updates rather than functional or environmental performance differences.

Q: What additional electrical specifications does the 5646728-1 provide?

A: The 5646728-1 provides specified current rating (1.5 A), voltage rating (750Vrms), and contact finish thickness (30.0µin / 0.76µm). The 114281 does not include these specifications in available documentation. The 5646728-1 also incorporates upper shield features as part of the Z-PACK series design.

Q: What is the packaging difference between these components?

A: The 114281 packaging is not specified in available documentation. The 5646728-1 is supplied in tube packaging, which is standard for high-position-count backplane connectors and facilitates automated assembly processes.

Q: Are there any secondary substitute options for the 114281?

A: The 5646728-1 is the primary manufacturer-recommended substitute. The 5646728-1 documentation references additional substitute part numbers HM2R95PA8100N9LF and HM2R95PA8108N9LF within the same Z-PACK series, which may be evaluated for specific application requirements.
