Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Würth Elektronik 662105145021 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 5
• Pitch - mating: 0.118" (3.00mm)
• Mounting type: Surface Mount
• Style: Board to Cable/Wire
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Current rating: 5A
• Voltage rating: 250V
• Material flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The Adam Tech DML-1-05-A-H-T-A-TSMT-T/R meets all critical parameters and qualifies as a direct substitute. Variations in insulation material (LCP versus Polyamide PA6T) and operating temperature range do not preclude substitution when the application requirements fall within the substitute part's specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the Würth Elektronik 662105145021 and Adam Tech DML-1-05-A-H-T-A-TSMT-T/R are active production parts with ROHS3 compliance and REACH unaffected status, qualifying them for use in regulated applications.

The primary distinction between these parts lies in operating temperature range and insulation material composition. The Würth Elektronik part operates from -40°C to 105°C with Liquid Crystal Polymer insulation, while the Adam Tech substitute operates from -25°C to 85°C with Polyamide (PA6T) insulation. Selection between these parts should be based on the specific operating temperature requirements of the application. Applications requiring operation below -25°C or above 85°C must use the Würth Elektronik part. Applications operating within the -25°C to 85°C envelope may use either part without functional compromise.

Both parts carry identical electrical ratings (5A current, 250V voltage), identical mechanical configuration (5 positions, 3.00mm pitch, shrouded 4-wall design), and identical contact geometry and finish specifications. Solder retention features are present on both parts, ensuring reliable assembly performance.

Frequently Asked Questions (FAQ)

Q: Can the Adam Tech DML-1-05-A-H-T-A-TSMT-T/R be used as a direct replacement for the Würth Elektronik 662105145021?

A: Yes, provided the application operating temperature remains within -25°C to 85°C. Both parts share identical electrical ratings, mechanical dimensions, pitch, shrouding configuration, and contact specifications. The parts are mechanically and electrically interchangeable within this temperature range.

Q: What is the key difference between these two connector headers?

A: The primary differences are operating temperature range and insulation material. The Würth Elektronik part operates from -40°C to 105°C with LCP insulation, while the Adam Tech part operates from -25°C to 85°C with Polyamide (PA6T) insulation. Both parts meet UL94 V-0 flammability requirements and carry identical electrical and mechanical specifications.

Q: Are both parts available in the same packaging format?

A: Yes. Both the Würth Elektronik 662105145021 and Adam Tech DML-1-05-A-H-T-A-TSMT-T/R are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Do these connectors support the same current and voltage ratings?

A: Yes. Both parts are rated for 5A current and 250V voltage, with identical contact finish (tin) and contact material specifications (copper alloy and brass respectively). The voltage rating difference notation (250V versus 250VAC) does not indicate a functional difference in this connector category.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry UL94 V-0 material flammability ratings. Both have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Can these parts be used interchangeably in high-temperature applications?

A: No. Applications requiring sustained operation above 85°C must use the Würth Elektronik 662105145021, which is rated to 105°C. The Adam Tech substitute is limited to 85°C maximum operating temperature.
