Key Parameters

Substitute Part Grouping Explanation

The 87409-120LF is a direct substitute within the Rib-Cage™ III series. Substitution eligibility is determined by the following critical parameters that must remain identical:

• Number of positions: 40
• Number of rows: 2
• Pitch - mating: 0.050" (1.27mm)
• Row spacing - mating: 0.050" (1.27mm)
• Connector type: Header
• Contact type: Male Pin
• Mounting type: Surface Mount
• Termination: Solder
• Fastening type: Push-Pull
• Operating temperature range: -55°C to 130°C
• Current rating: 1A (DC)
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The primary difference between the main part and its substitute relates to RoHS compliance status and contact finish material on the post termination.

Parameter Comparison

Engineering Selection Recommendations

Both the 87409-120 and 87409-120LF are active production parts within the Rib-Cage™ III series and share identical mechanical and electrical specifications. Selection between these parts should be based on regulatory and compliance requirements:

The 87409-120LF is RoHS compliant and features tin post finish, making it suitable for applications subject to RoHS directives and lead-free manufacturing requirements. The 87409-120 uses tin-lead post finish and is RoHS non-compliant, appropriate for applications without RoHS restrictions or legacy systems.

Both parts maintain identical performance characteristics across all critical parameters including pitch, row spacing, current rating, temperature range, and flammability rating. The choice between these parts does not affect electrical or mechanical compatibility with mating connectors or PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can 87409-120LF replace 87409-120 in existing designs?

A: Yes. Both parts are mechanically and electrically identical. The primary difference is RoHS compliance status and post finish material. Substitution is valid provided the application does not have specific restrictions on lead content or RoHS compliance requirements.

Q: What is the significance of the "LF" designation in 87409-120LF?

A: The "LF" suffix indicates lead-free composition, specifically referring to the tin post finish instead of tin-lead. This designation aligns with RoHS compliance requirements.

Q: Are the mating dimensions identical between these parts?

A: Yes. Both parts maintain identical pitch (0.050" / 1.27mm), row spacing (0.050" / 1.27mm), and contact geometry. Mating compatibility with corresponding receptacle connectors is identical.

Q: What is the operating temperature range for both parts?

A: Both the 87409-120 and 87409-120LF operate across -55°C to 130°C, providing identical thermal performance for general purpose and military applications.

Q: Are there any differences in current handling capability?

A: No. Both parts are rated for 1A DC current. Electrical performance and current capacity are identical.

Q: What packaging format is used for these parts?

A: Both parts are supplied in tube packaging, standard for surface mount connector headers.
