Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Erni 103670 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 133 (95 + 38 Ground)
• Pitch: 0.079" (2.00mm)
• Number of Rows: 5 + 2
• Connector Style: B 19
• Connector Type: Header, Male Pins
• Mounting Type: Through Hole
• Termination: Press-Fit
• Contact Finish: Gold
• Operating Temperature Range: -55°C ~ 125°C

Both identified substitute parts, TE Connectivity AMP Connectors 5352033-1 and 5352127-1, satisfy all mandatory matching parameters. These parts are classified as active products within the Z-PACK series, providing direct functional equivalence to the obsolete 103670. The substitutes maintain identical electrical and mechanical interfaces while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5352033-1

The 5352033-1 is the manufacturer-recommended substitute for the obsolete 103670. This part maintains complete electrical and mechanical compatibility while offering active product status. The part is RoHS compliant and carries MSL 1 rating, indicating no moisture sensitivity constraints. Electrical specifications of 1.5 A current rating and 500Vrms voltage rating provide adequate performance margins for standard backplane applications.

Secondary Substitute: TE Connectivity AMP Connectors 5352127-1

The 5352127-1 provides an alternative active substitute with identical core specifications to the 5352033-1. This variant includes an alignment strip feature and is designated for CompactPCI P3 connector usage. The part maintains equivalent electrical performance and compliance certifications. Selection between 5352033-1 and 5352127-1 depends on application-specific requirements for alignment features and CompactPCI compatibility.

Both substitutes are available in tube packaging and maintain the same press-fit termination and gold contact finish as the original 103670. The transition from the obsolete ERMET series to the active Z-PACK series represents a direct product line evolution within TE Connectivity's connector portfolio.

Frequently Asked Questions (FAQ)

Q: Can the 5352033-1 or 5352127-1 directly replace the 103670 in existing designs?

A: Yes. Both substitute parts maintain identical connector style (B 19), position count (133), pitch (2.00mm), row configuration (5 + 2), mounting type (through hole), and termination method (press-fit). The physical and electrical interfaces are equivalent, enabling direct substitution without PCB redesign.

Q: What is the difference between the 5352033-1 and 5352127-1?

A: The primary differences are the inclusion of an alignment strip feature in the 5352127-1 and its designation for CompactPCI P3 applications. Both parts share identical electrical specifications, temperature ratings, and compliance certifications. Selection depends on whether the alignment strip feature is required for the application.

Q: Are there any compliance or certification differences between the 103670 and its substitutes?

A: The 103670 is ROHS3 compliant, while both substitutes are RoHS compliant. All three parts carry MSL 1 rating and share the same ECCN (EAR99) and HTSUS classifications. The substitutes provide equivalent or improved compliance status for ongoing procurement.

Q: What is the contact finish thickness specification for the 103670?

A: The contact finish thickness for the 103670 is not specified in the available documentation. Both substitute parts specify 30.0µin (0.76µm) gold contact finish thickness, providing documented electrical contact performance.

Q: Are electrical ratings specified for the 103670?

A: Current and voltage ratings are not specified for the 103670. The substitute parts provide documented ratings of 1.5 A current and 500Vrms voltage, establishing performance parameters for backplane applications.

Q: What packaging format is available for the substitute parts?

A: Both 5352033-1 and 5352127-1 are supplied in tube packaging. The original 103670 packaging format is not specified in the available documentation.

Q: Can the 5352127-1 be used in non-CompactPCI applications?

A: Yes. The CompactPCI P3 designation indicates the intended application, but the part's electrical and mechanical specifications support use in standard backplane connector applications. The alignment strip feature provides additional positioning control regardless of application type.
