TE Connectivity Erni 104153 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 104153 is a 250-position backplane connector header with male pins, featuring 0.079" (2.00mm) pitch and press-fit termination. This connector is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The part is constructed with 8 + 2 rows of positions (200 signal + 50 ground), through-hole mounting, and gold-plated contacts suitable for operating temperatures from -55°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity Erni 104153 is determined by strict equivalence across the following parameters: connector type (header, male pins), number of positions (250 with 200 + 50 ground configuration), pitch (0.079" / 2.00mm), row configuration (8 + 2), mounting method (through hole), termination technology (press-fit), connector style (E 25), contact finish (gold), and operating temperature range (-55°C ~ 125°C).

The identified substitute parts—TE Connectivity AMP Connectors 5646357-1 and 646357-1—satisfy all core electrical and mechanical parameters. Both parts are active products from the Z-PACK series, providing functional equivalence to the obsolete Erni 104153. The substitutes additionally provide specified electrical ratings (1.5 A current, 750Vrms voltage) not documented in the original part specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5646357-1

The 5646357-1 is the recommended substitute for the obsolete Erni 104153. This part maintains full electrical and mechanical compatibility across all specified parameters while offering active product status and RoHS compliance. The Z-PACK series design provides documented electrical performance (1.5 A, 750Vrms) and is available in higher inventory quantities (1469 units).

Secondary Substitute: TE Connectivity AMP Connectors 646357-1

The 646357-1 provides equivalent mechanical and electrical functionality to the 104153 and is also an active product. However, this part carries RoHS non-compliant status and REACH-affected designation, making it unsuitable for applications requiring regulatory compliance. Selection of this part should be limited to legacy systems or applications where RoHS compliance is not mandated.

Both substitutes are manufactured by TE Connectivity and utilize identical connector geometry, pitch, and termination technology, ensuring direct functional replacement in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the 5646357-1 directly replace the obsolete 104153 in existing designs?

A: Yes. The 5646357-1 maintains identical electrical and mechanical specifications across all critical parameters: 250-position configuration, 0.079" (2.00mm) pitch, 8 + 2 row layout, through-hole press-fit termination, E 25 connector style, and gold contact finish. No PCB redesign is required.

Q: What is the difference between the 5646357-1 and 646357-1 substitutes?

A: Both parts are functionally equivalent and interchangeable from an electrical and mechanical standpoint. The primary distinction is regulatory compliance: the 5646357-1 is RoHS compliant, while the 646357-1 is RoHS non-compliant and REACH-affected. For new designs and applications subject to environmental regulations, the 5646357-1 is the appropriate selection.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The original 104153 is supplied in tray packaging, while both substitute parts (5646357-1 and 646357-1) are supplied in tube packaging. Verify that tube packaging is compatible with receiving and storage procedures in your manufacturing environment.

Q: What electrical performance specifications apply to the substitutes?

A: The 5646357-1 and 646357-1 are rated for 1.5 A continuous current and 750Vrms voltage. These ratings were not documented for the original 104153 part. Confirm that these electrical parameters meet or exceed the requirements of your application.

Q: Is the contact finish thickness specification important for substitution?

A: The substitutes specify 30.0µin (0.76µm) gold contact finish thickness, while the original part does not document this parameter. This thickness is standard for TE Connectivity press-fit connectors and provides equivalent contact reliability and durability for the operating temperature range (-55°C ~ 125°C).

Q: What is the moisture sensitivity level for these connectors?

A: All three parts—the original 104153 and both substitutes (5646357-1 and 646357-1)—carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage or handling.
