Substitute Part Grouping Explanation

Substitution eligibility for the SMM-104-02-F-D-TR is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part SMM-104-02-F-D-K-TR qualifies as a direct equivalent based on the following matching criteria:

Identical electrical specifications: 8-position receptacle configuration, 0.079" (2.00mm) pitch, 2-row layout with 0.079" row spacing, 3.2A per contact current rating, and 350VAC voltage rating.

Identical mechanical specifications: Surface mount solder termination, female socket contact type, gold mating contact finish, beryllium copper contact material, and liquid crystal polymer insulation.

Identical environmental and compliance ratings: -55°C to 125°C operating temperature range, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level.

The primary distinction between these parts is packaging configuration: SMM-104-02-F-D-TR is supplied in standard packaging, while SMM-104-02-F-D-K-TR is supplied in Tape & Reel (TR) format with Pick and Place features. This difference affects manufacturing workflow and procurement logistics but does not alter functional or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both SMM-104-02-F-D-TR and SMM-104-02-F-D-K-TR maintain Active product status from Samtec Inc., confirming ongoing manufacturer support and availability. Both parts comply with RoHS3 and REACH regulations where applicable, and both carry EAR99 export classification.

Selection between these parts should be based on manufacturing and procurement requirements:

SMM-104-02-F-D-TR is appropriate for applications requiring standard packaging with manual assembly workflows or lower-volume production runs.

SMM-104-02-F-D-K-TR is appropriate for automated assembly environments utilizing pick-and-place equipment, as Tape & Reel packaging with Pick and Place features optimizes high-volume surface mount manufacturing processes.

From an electrical and mechanical standpoint, both parts are functionally interchangeable and will perform identically within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are SMM-104-02-F-D-TR and SMM-104-02-F-D-K-TR electrically identical?

A: Yes. Both parts share identical electrical specifications including 8-position configuration, 0.079" (2.00mm) pitch, 3.2A per contact current rating, and 350VAC voltage rating. They will function identically in circuit applications.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. SMM-104-02-F-D-TR uses standard packaging, while SMM-104-02-F-D-K-TR is supplied in Tape & Reel (TR) format with Pick and Place features optimized for automated assembly.

Q: Can I substitute SMM-104-02-F-D-K-TR for SMM-104-02-F-D-TR in my design?

A: Yes, from a functional and electrical perspective. However, verify that your assembly process can accommodate Tape & Reel packaging. If your manufacturing uses manual assembly or does not have pick-and-place capability, the standard packaging format may be more practical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are Active status products, UL94 V-0 rated, RoHS3 compliant, and REACH unaffected. Both carry MSL 1 moisture sensitivity rating and operate across -55°C to 125°C.

Q: Which part should I specify for high-volume production?

A: SMM-104-02-F-D-K-TR in Tape & Reel format is optimized for high-volume automated assembly. Standard packaging (SMM-104-02-F-D-TR) is suitable for lower volumes or manual assembly workflows.

Q: Are there any mechanical compatibility issues between these parts?

A: No. Both parts have identical mechanical specifications including surface mount solder termination, 0.140" (4.66mm) insulation height, square contact shape, and beryllium copper contact material.
