Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 58334-103 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 24 positions arranged in 4 rows × 6 columns
• Pitch Specification: 0.079" (2.00mm) center-to-center spacing
• Connector Type: Header with male pins
• Mounting Method: Through-hole PCB mounting
• Termination Technology: Press-fit contact termination
• Contact Material: Gold plating
• Flammability Compliance: UL94 V-0 rating
• Moisture Sensitivity: MSL 1 classification

The substitute part 58334-103LF meets all these parameters while offering improved product status and compliance documentation.

Frequently Asked Questions (FAQ)

Q: Are the 58334-103 and 58334-103LF mechanically interchangeable?

A: Yes. Both parts feature identical 24-position configurations with 0.079" (2.00mm) pitch, through-hole mounting, and press-fit termination. PCB footprints and mounting hole patterns are identical.

Q: What does the "LF" suffix in 58334-103LF indicate?

A: The "LF" designation indicates lead-free contact plating, which aligns with RoHS compliance requirements. The gold contact finish remains unchanged.

Q: Can I use 58334-103LF as a direct replacement in existing designs?

A: Yes. The 58334-103LF maintains full electrical and mechanical compatibility with the original 58334-103 specification. No PCB redesign or circuit modification is required.

Q: What is the difference in REACH status between these parts?

A: The original 58334-103 is listed as REACH Unaffected, while the 58334-103LF is REACH Affected. The 58334-103LF includes full REACH compliance documentation, which is required for new designs and ongoing procurement in regulated markets.

Q: Are there inventory considerations when switching to the substitute part?

A: The 58334-103LF is available in higher quantities (1073 Pcs) compared to the obsolete 58334-103 (736 Pcs). The substitute is packaged in tubes, providing standardized handling for production environments.

Q: Does the substitute part meet the same flammability and moisture sensitivity requirements?

A: Yes. Both parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification.
