Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T2M-115-01-S-D-TH is determined by the following critical parameters:

Primary Matching Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 30
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Insulation Material: Liquid Crystal Polymer (LCP)

Acceptable Variation Parameters:

• Operating Temperature range (if application requirement is within the substitute's range)
• Contact Length - Mating (if not specified in main part)
• Insulation Height (minor variations acceptable if mechanical fit permits)
• Features (additional features such as keying slots or solder retention do not preclude substitution)
• Moisture Sensitivity Level classification

The identified substitutes maintain electrical and mechanical compatibility through matching core connector architecture, contact configuration, and material specifications.

Parameter Comparison

Engineering Selection Recommendations

All three connectors maintain active product status with ROHS3 compliance, ensuring regulatory alignment and ongoing manufacturer support.

T2M-115-01-S-D-TH-WT is functionally equivalent to the main part with identical electrical and mechanical specifications. The addition of solder retention feature provides enhanced manufacturing robustness without altering connector compatibility. Operating temperature range and current rating remain unchanged. This variant is suitable for direct substitution where solder retention is beneficial or neutral to the application.

LTMM-115-02-S-D shares core connector architecture and electrical characteristics but operates within a reduced temperature range (-55°C ~ 105°C versus -55°C ~ 125°C). The insulation height is 0.190" (4.83mm) compared to 0.228" (5.80mm), representing a 0.038" reduction. The addition of a keying slot provides polarization capability. Current rating is not specified for this part. This connector is suitable for applications where the lower maximum operating temperature is acceptable and where keying functionality is required or tolerated.

Selection between substitutes depends on application-specific requirements regarding operating temperature limits, mechanical fit constraints, and keying requirements.

Frequently Asked Questions (FAQ)

Q: Can T2M-115-01-S-D-TH-WT be used as a direct replacement for T2M-115-01-S-D-TH?

A: Yes. Both connectors share identical pitch, position count, row configuration, contact material, finish specifications, and operating temperature range. The solder retention feature in the -WT variant does not affect electrical or mechanical compatibility.

Q: What is the primary difference between T2M-115-01-S-D-TH and LTMM-115-02-S-D?

A: The LTMM-115-02-S-D operates at a maximum temperature of 105°C compared to 125°C for the T2M series. Additionally, the LTMM variant has a reduced insulation height of 0.190" versus 0.228", and includes a keying slot for polarization. Core electrical specifications including pitch, position count, and contact materials remain identical.

Q: Is the LTMM-115-02-S-D suitable for high-temperature applications?

A: The LTMM-115-02-S-D is rated for -55°C to 105°C operation. Applications requiring sustained operation above 105°C should use the T2M-115-01-S-D-TH or T2M-115-01-S-D-TH-WT, which are rated to 125°C.

Q: Does the keying slot on LTMM-115-02-S-D affect compatibility?

A: The keying slot is a polarization feature that prevents incorrect mating orientation. If the mating connector is designed for keyed operation, the LTMM-115-02-S-D is required. If keying is not part of the system design, the keying slot does not prevent use of this connector.

Q: Are all three connectors RoHS compliant?

A: Yes. All three parts are ROHS3 compliant, meeting regulatory requirements for restricted substance elimination.

Q: What is the significance of the insulation height difference between T2M and LTMM series?

A: The insulation height affects the overall connector profile and mechanical fit on the PCB. The T2M series at 0.228" (5.80mm) provides greater insulation height compared to the LTMM series at 0.190" (4.83mm). Mechanical fit verification is required if substituting between these series to ensure clearance compatibility with surrounding components.

Q: Can current rating be assumed equal across all three connectors?

A: The T2M-115-01-S-D-TH and T2M-115-01-S-D-TH-WT are both rated at 3.8A. The current rating for LTMM-115-02-S-D is not specified in the provided data. Applications with defined current requirements should verify compatibility before selecting the LTMM variant.
