Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91910-21421 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

• Connector type and contact configuration (Header, Center Strip Contacts)
• Position count (21 positions)
• Contact pitch (0.039" / 1.00mm)
• Row configuration (2 rows)
• Surface mount mounting type
• Contact finish material and thickness (Gold or Gold, GXT™ at 15.0µin)
• Physical dimensions (6mm mated stacking height, 0.107" height above board)
• Functional features (Board Guide, Solder Retention)

The 91910-21421LF meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The 91910-21421LF is the direct substitute for the obsolete 91910-21421. Selection of the 91910-21421LF is supported by the following factors:

• Identical electrical and mechanical specifications across all critical parameters
• Active product status ensures ongoing availability and supply chain continuity
• RoHS compliance of the 91910-21421LF provides regulatory advantage over the non-compliant original part
• REACH affected status of the 91910-21421LF indicates current regulatory documentation and compliance tracking
• Equivalent MSL rating (1 / Unlimited) maintains identical handling and storage requirements
• Identical ECCN and HTSUS classifications confirm trade compliance equivalence

Frequently Asked Questions (FAQ)

Q: Can the 91910-21421LF be used as a direct replacement for the 91910-21421?

A: Yes. The 91910-21421LF is electrically and mechanically identical to the 91910-21421 across all specified parameters, including connector type, position count, pitch, mounting type, contact finish, and physical dimensions. The primary difference is product status and compliance certifications.

Q: What is the significance of the "LF" suffix in the part number?

A: The "LF" designation typically indicates lead-free or compliance-related modifications. The 91910-21421LF is RoHS compliant, whereas the original 91910-21421 is not. This reflects updated manufacturing standards and regulatory requirements.

Q: Are there packaging differences between these parts?

A: The 91910-21421 packaging is not specified in the available data. The 91910-21421LF is supplied in tube packaging. Verify packaging requirements for your specific application and procurement process.

Q: Do these connectors have identical moisture sensitivity requirements?

A: Yes. Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence in connector type, position count (21), pitch (0.039" / 1.00mm), row configuration (2), mounting type (surface mount), contact finish (gold at 15.0µin thickness), mated stacking height (6mm), height above board (0.107"), and functional features (board guide, solder retention).
