TE Connectivity AMP Connectors 5646357-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 5646357-9 is a 250-position backplane connector header with male pins, designed for through-hole mounting applications. This connector features a 2.00mm pitch and press-fit termination, supporting 1.5A current at 750Vrms across an operating temperature range of -55°C to 125°C. The connector is part of the Z-PACK series and maintains active product status with RoHS compliance. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits equivalent component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5646357-9 is determined by strict equivalence across the following critical parameters:

Position and Pitch Compatibility: The substitute part must maintain 250 total positions (200 + 50 ground) with an identical 0.079" (2.00mm) pitch and 8 + 2 row configuration to ensure mechanical and electrical interchangeability within the backplane connector interface.

Electrical Performance: The substitute must support the same connector usage classification (backplane connectors), mounting type (through hole), and termination method (press-fit). While current and voltage ratings may vary within acceptable operational ranges, the substitute must not fall below the minimum electrical requirements of the primary application.

Environmental and Compliance Requirements: The substitute must maintain compatibility with the operating temperature range of -55°C to 125°C and comply with RoHS standards. MSL rating of 1 (Unlimited) ensures no moisture sensitivity constraints during storage and handling.

Contact Finish and Reliability: Gold or equivalent noble metal contact finishes ensure consistent electrical performance and corrosion resistance across both parts.

The HARTING 17122502201 meets all substitution criteria through identical position count, pitch, row configuration, mounting type, termination method, temperature range, and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TE Connectivity 5646357-9 remains the specified component for applications requiring the full 1.5A current rating and 750Vrms voltage specification. This part is actively manufactured and maintains full RoHS compliance with unlimited moisture sensitivity rating.

Substitute Part Selection: The HARTING 17122502201 is suitable for applications where the current requirement does not exceed 1.0A. This substitute maintains mechanical and thermal equivalence, identical position and pitch configuration, and active product status. Both parts comply with RoHS standards and share the same MSL rating, ensuring equivalent handling and storage requirements.

Compliance Considerations: Both parts are active products with RoHS compliance certification. The HARTING part carries ROHS3 compliance designation, while the TE Connectivity part carries standard RoHS compliance. Both parts are classified under identical HTSUS code 8536.69.4040 and ECCN EAR99, supporting equivalent regulatory and trade compliance.

Electrical Derating: Applications operating at or near 1.5A should retain the TE Connectivity 5646357-9 to maintain specified current margin. The HARTING substitute is appropriate for designs operating at 1.0A or below, providing adequate safety margin within its rated specification.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 17122502201 be used as a direct replacement for the TE Connectivity 5646357-9 in all applications?

A: The HARTING 17122502201 is mechanically and thermally equivalent but carries a lower current rating of 1.0A versus 1.5A for the TE Connectivity part. Substitution is valid only for applications where circuit current does not exceed 1.0A. Voltage rating information for the HARTING part is not specified in available documentation.

Q: Are the connector pitch and position configurations identical between these parts?

A: Yes. Both parts feature 250 total positions (200 + 50 ground), 0.079" (2.00mm) pitch, and 8 + 2 row configuration. Mechanical interchangeability is confirmed for backplane connector interfaces.

Q: What is the difference between "Backplane" and "Backplane-to-Daughtercard" connector usage classifications?

A: Both classifications indicate backplane connector applications. The HARTING designation specifies daughtercard interface compatibility, which is compatible with general backplane usage. No functional limitation exists for standard backplane applications.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints. Identical handling, storage, and packaging procedures apply to both components.

Q: What is the significance of the contact finish difference between Gold and Gold-Palladium?

A: Both finishes provide equivalent corrosion resistance and electrical performance for backplane connector applications. Gold-Palladium offers enhanced wear resistance in high-cycle mating applications. For standard backplane installations, both finishes are functionally equivalent.

Q: Are both parts currently in active production?

A: Yes. Both the TE Connectivity 5646357-9 and HARTING 17122502201 maintain active product status with current manufacturing and distribution availability.
