Molex 0705430045 Equivalent & Substitute Parts

Part Overview

The Molex 0705430045 is an 11-position vertical header connector with 0.100" (2.54mm) pitch, designed for through-hole board-to-cable/wire applications. This shrouded 4-wall connector features tin-plated phosphor bronze contacts and is rated for 250V operation across automotive, general purpose, industrial, and medical applications. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to provide design flexibility, supply chain alternatives, and equivalent functional performance when the primary part is unavailable or when specific application requirements necessitate alternative specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0705430045 is determined by strict alignment with the following critical parameters:

• Connector Type & Contact Configuration: Must be a header with male pin contacts
• Position Count & Pitch: Must maintain 11 positions at 0.100" (2.54mm) mating pitch
• Row Configuration: Single-row layout required
• Mounting & Termination: Through-hole solder termination mandatory
• Shrouding: 4-wall shrouded design required
• Electrical Ratings: Minimum 250V voltage rating; contact finish must be tin-plated
• Compliance: RoHS3 compliance and UL94 V-0 flammability rating required

The Adam Tech CDR-11-TS meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0705430045 and Adam Tech CDR-11-TS maintain Active product status with full RoHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on the following provided specifications:

Molex 0705430045 is suitable for applications requiring the extended operating temperature range of -40°C to 105°C, particularly in automotive and industrial environments subject to thermal extremes.

Adam Tech CDR-11-TS is suitable for applications within the -25°C to 85°C operating range and provides explicit current rating specification of 2.5A per contact. Minor dimensional variations in contact post length (0.138" versus 0.130") and insulation height (0.469" versus 0.465") fall within acceptable mechanical tolerances for standard through-hole PCB applications.

Both parts satisfy the core electrical and mechanical requirements for 11-position 2.54mm pitch header applications with identical shrouding, termination, and contact finish specifications.

Frequently Asked Questions (FAQ)

Q: Can the Adam Tech CDR-11-TS directly replace the Molex 0705430045 in existing designs?

A: Yes, for applications operating within the -25°C to 85°C temperature range. The CDR-11-TS maintains identical pitch, position count, shrouding, and contact configuration. Minor dimensional variations in post length and insulation height are within standard PCB assembly tolerances for through-hole connectors.

Q: What is the primary difference between these two parts?

A: The Molex part supports extended temperature operation (-40°C to 105°C) while the Adam Tech part is rated -25°C to 85°C. The Adam Tech part explicitly specifies 2.5A current rating per contact. Both parts are electrically and mechanically equivalent for standard applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Molex 0705430045 and Adam Tech CDR-11-TS carry ROHS3 compliance certification with UL94 V-0 flammability rating and MSL 1 (unlimited) moisture sensitivity level.

Q: Does the difference in contact post length affect PCB compatibility?

A: No. The 0.008" (0.20mm) difference in contact post length (0.130" versus 0.138") is within standard manufacturing tolerances and does not affect through-hole PCB assembly or solder joint formation for standard board thicknesses.

Q: Which part should be selected for automotive applications?

A: The Molex 0705430045 is specified for automotive applications and supports the extended -40°C to 105°C temperature range typical of automotive thermal requirements. The Adam Tech CDR-11-TS is suitable for automotive applications within the -25°C to 85°C operating envelope.

Q: What is the packaging difference between these parts?

A: The Molex 0705430045 is supplied in tube packaging, while the Adam Tech CDR-11-TS is supplied in bag packaging. Both are suitable for production assembly; packaging selection depends on handling and storage requirements.
