Key Parameters

Substitute Part Grouping Explanation

The substitute part 63735-101LF is classified as a direct equivalent based on the following critical parameters that determine functional interchangeability:

• Connector Type & Style: Both parts are housing for male pins in rack and panel configuration
• Position Count & Coaxial Configuration: Both feature 4 coaxial positions with 2-row arrangement
• Mounting Architecture: Both utilize through-hole mounting with board guide features
• Physical Characteristics: Both maintain natural color finish and identical base product number (63735)
• Electrical Classification: Both are assigned identical ECCN (EAR99) and HTSUS codes
• Environmental Rating: Both feature MSL 1 (Unlimited) moisture sensitivity level

The primary distinction between these parts is the product status and compliance certification level, not functional or mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The 63735-101LF serves as the active production equivalent to the obsolete 63735-101. Selection between these parts should be based on regulatory and compliance requirements:

Use 63735-101LF when:

• New designs or production runs require RoHS compliance certification
• REACH compliance documentation is required for supply chain qualification
• Active product status and ongoing manufacturer support are necessary
• Bulk packaging accommodates production volume requirements

Use 63735-101 when:

• Legacy systems or repair applications specifically require the original obsolete part number
• RoHS non-compliance is acceptable for the application context
• Existing inventory must be consumed before transition to compliant alternatives

Both parts maintain identical mechanical and electrical characteristics, ensuring direct form-fit-function compatibility in rack and panel backplane connector applications.

Frequently Asked Questions (FAQ)

Q: Are 63735-101 and 63735-101LF mechanically interchangeable?

A: Yes. Both parts share identical connector type, position count (4 coaxial), row configuration (2 rows), mounting method (through hole), and board guide features. The "LF" designation in 63735-101LF indicates lead-free and RoHS compliance, not a mechanical variation.

Q: What is the significance of the product status difference?

A: The 63735-101 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 63735-101LF is active production, ensuring ongoing supply chain availability and manufacturer technical support.

Q: Does RoHS compliance affect connector performance?

A: RoHS compliance (63735-101LF) reflects material composition changes to eliminate restricted substances. Functional performance and electrical characteristics remain equivalent to the non-compliant version (63735-101).

Q: Can I use 63735-101LF as a direct replacement in existing assemblies designed for 63735-101?

A: Yes. The parts are functionally equivalent with identical mounting, position count, and connector style. Compliance certifications differ, but mechanical and electrical compatibility is maintained.

Q: What packaging options are available?

A: The 63735-101 packaging is not specified in available documentation. The 63735-101LF is supplied in bulk packaging suitable for production environments.

Q: Are there inventory considerations for part selection?

A: The 63735-101 has 744 pieces in stock (obsolete status). The 63735-101LF has 1359 pieces in stock (active status). For new applications, the active part ensures sustained availability.
