Substitute Part Grouping Explanation

Substitute parts TFM-115-22-L-D-A and TFM-115-32-L-D-A are functionally equivalent to TFM-115-12-L-D-A based on the following criteria:

All three parts share identical specifications for:

• Connector type, contact type, and gender (Header, Male Pin)
• Number of positions and row configuration (30 positions, 2 rows)
• Pitch and row spacing (0.050" / 1.27mm)
• Mounting type and termination method (Surface Mount, Solder)
• Electrical ratings (2.9A per contact, 275VAC)
• Operating temperature range (-55°C ~ 125°C)
• Material and compliance certifications (LCP insulation, UL94 V-0, ROHS3 Compliant)

The only variable parameter among these parts is insulation height:

• TFM-115-12-L-D-A: 0.290" (7.37mm)
• TFM-115-22-L-D-A: 0.360" (9.14mm)
• TFM-115-32-L-D-A: 0.435" (11.05mm)

Selection between these variants depends solely on PCB stack-up and mating connector clearance requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with full compliance to ROHS3 and REACH requirements. Selection between TFM-115-12-L-D-A, TFM-115-22-L-D-A, and TFM-115-32-L-D-A is determined by mechanical fit within the application's PCB stack-up and mating connector geometry. The insulation height differential accommodates varying clearance requirements without affecting electrical performance or thermal characteristics. All variants carry identical certifications (UL94 V-0, MSL 1) and support the full operating temperature range. Inventory availability is adequate across all three options, with TFM-115-32-L-D-A offering the highest stock level at 1396 pieces.

Frequently Asked Questions (FAQ)

Q: Can TFM-115-22-L-D-A or TFM-115-32-L-D-A be used as direct replacements for TFM-115-12-L-D-A?

A: Yes, provided the application's mechanical constraints permit the increased insulation height. All three parts are electrically and functionally identical with respect to contact configuration, pitch, current rating, voltage rating, and operating temperature. The only difference is insulation height, which affects PCB clearance and mating connector compatibility.

Q: What determines which insulation height variant to select?

A: Insulation height is selected based on the available vertical space on the PCB and the mating connector's insertion depth requirements. TFM-115-12-L-D-A (0.290") is the shortest, TFM-115-22-L-D-A (0.360") is intermediate, and TFM-115-32-L-D-A (0.435") is the tallest. Verify mating connector specifications to ensure proper engagement without interference.

Q: Are there any electrical performance differences between these three parts?

A: No. All three parts share identical electrical specifications: 2.9A per contact, 275VAC rating, -55°C to 125°C operating temperature, and identical contact materials and finishes.

Q: Do all three parts have the same compliance certifications?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the packaging format for these parts?

A: All three parts are supplied in Tube packaging as new original stock.
