ISDF-20-D-R Equivalent & Substitute Parts

Part Overview

The ISDF-20-D-R is a 40-position rectangular connector insulator housing from Samtec Inc.'s Tiger Eye™ ISDF series. This component serves as the insulator housing for female socket contacts with 0.050" (1.27mm) pitch spacing in a 2-row configuration. The part is actively manufactured and ROHS3 compliant, designed for crimp termination applications with latch lock fastening. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, allowing for interchangeability in applications where the housing specifications remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISDF-20-D-R is determined by strict equivalence across the following critical parameters:

• Number of positions: 40
• Pitch spacing: 0.050" (1.27mm)
• Number of rows: 2
• Row spacing: 0.050" (1.27mm)
• Contact type: Female Socket
• Connector type: Insulator Housing
• Mounting type: Free Hanging (In-Line)
• Contact termination: Crimp
• Fastening type: Latch Lock
• Insulation material: Liquid Crystal Polymer (LCP)
• Operating temperature range: -55°C to 125°C
• Product status: Active

Parts meeting all these criteria are classified as direct substitutes within the Tiger Eye™ ISDF series.

Parameter Comparison

Engineering Selection Recommendations

Both the ISDF-20-D-R and ISDF-20-D maintain identical electrical and mechanical specifications within the Tiger Eye™ ISDF series. Both parts are actively manufactured with ROHS3 compliance and MSL Level 1 rating, indicating no moisture sensitivity constraints during storage or handling. Selection between these parts should be based on inventory availability and lead time requirements, as all functional parameters are equivalent. The ISDF-20-D currently maintains higher inventory levels (1277 pcs) compared to the ISDF-20-D-R (969 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can ISDF-20-D be used as a direct replacement for ISDF-20-D-R?

A: Yes. Both parts share identical specifications across all critical parameters: 40 positions, 0.050" pitch, 2-row configuration, female socket contacts, crimp termination, latch lock fastening, LCP insulation material, and -55°C to 125°C operating range. Both are ROHS3 compliant and actively manufactured.

Q: Are there any differences in compliance or certifications between these parts?

A: Both parts are ROHS3 compliant with MSL Level 1 rating. The ISDF-20-D carries REACH Unaffected status. Both share identical ECCN and HTSUS classifications for regulatory purposes.

Q: What determines substitution eligibility for ISDF-20-D-R?

A: Substitution is determined by equivalence in connector position count, pitch spacing, row configuration, contact type, mounting method, termination type, fastening mechanism, insulation material, and operating temperature range. All these parameters must match exactly.

Q: Are contacts included with these housing parts?

A: No. Both ISDF-20-D-R and ISDF-20-D are insulator housings supplied without contacts. Contacts must be sourced separately and crimped into the housing.

Q: What is the significance of the base product number ISDF-20?

A: The base product number ISDF-20 identifies the core connector family. Suffix designations (such as -D and -R) indicate specific variants within this family, but both variants maintain the same fundamental 40-position, 1.27mm pitch architecture.
