Substitute Part Grouping Explanation

Substitution eligibility for the ID1A-6S-2.54SF(21) is determined by strict equivalence across the following critical parameters:

• Series designation (ID1A)
• Card type (SIM Card)
• Number of positions (6)
• Connector type (Connector and Ejector)
• Insertion and removal method (Hinged Lid)
• Mounting configuration (Surface Mount, Right Angle)
• Height above board (0.096" / 2.45mm)
• Contact finish (Gold)
• Board guide feature presence

The ID1A-6S-2.54SF(81) qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction lies in packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The ID1A-6S-2.54SF(81) is functionally equivalent to the ID1A-6S-2.54SF(21) across all electrical and mechanical specifications. Selection between these parts should be based on the following factors:

RoHS Compliance: The ID1A-6S-2.54SF(81) is RoHS compliant, whereas the ID1A-6S-2.54SF(21) is non-compliant. For applications subject to RoHS regulations or customer requirements, the (81) variant is the appropriate selection.

Packaging Format: The ID1A-6S-2.54SF(81) is supplied in Cut Tape (CT) packaging, while the ID1A-6S-2.54SF(21) packaging format is unspecified. Packaging selection should align with assembly process requirements and inventory management protocols.

Product Status: Both parts are classified as obsolete. Long-term availability should be confirmed with the manufacturer or authorized distributors prior to design commitment.

Frequently Asked Questions (FAQ)

Q: Can the ID1A-6S-2.54SF(81) be used as a direct replacement for the ID1A-6S-2.54SF(21)?

A: Yes. The ID1A-6S-2.54SF(81) is electrically and mechanically equivalent. Both connectors share identical position count, mounting configuration, height profile, contact finish, and board guide features. The primary differences are packaging format and RoHS compliance status.

Q: What is the significance of the part number suffix (21) versus (81)?

A: The suffix designates packaging and compliance variants within the ID1A series. The (21) and (81) variants are functionally identical but differ in RoHS status and packaging format.

Q: Are there any compatibility concerns when substituting the ID1A-6S-2.54SF(81) for the ID1A-6S-2.54SF(21)?

A: No compatibility concerns exist from an electrical or mechanical standpoint. Both connectors are designed for identical PCB footprints and SIM card interface specifications. Compliance requirements should be evaluated based on application and regulatory jurisdiction.

Q: What does RoHS compliance mean for this connector?

A: RoHS compliance indicates the connector meets restrictions on hazardous substances as defined by applicable regulations. The ID1A-6S-2.54SF(81) meets these requirements, while the ID1A-6S-2.54SF(21) does not. Selection should reflect application compliance obligations.

Q: How should packaging format influence component selection?

A: Packaging format affects handling, storage, and assembly processes. Cut Tape (CT) packaging is suitable for automated pick-and-place assembly. Packaging selection should align with manufacturing equipment capabilities and inventory management requirements.
