Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HFW4R-1STAE1LF is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of Positions: 4
• Pitch: 0.039" (1.00mm)
• Mounting Type: Surface Mount, Right Angle
• Connector/Contact Type: Contacts, Bottom
• Termination: Solder
• FFC, FCB Thickness: 0.30mm
• Height Above Board: 0.075" (1.90mm)
• Material Flammability Rating: UL94 V-0
• RoHS Compliance

Identified Substitutes:

1. HFW4R-1STAE1H1LF (Amphenol ICC) – Direct equivalent with active product status. Maintains all critical electrical and mechanical parameters. Housing material differs (LCP, Halogen Free vs. PA6T, Nylon 6T, Glass Filled) but meets equivalent performance specifications.

2. 2005290040 (Molex Easy-On 200529 Series) – Cross-manufacturer substitute meeting core positional, pitch, and mounting requirements. Functional compatibility confirmed through matching connector type, termination method, and board height. Differences in contact finish (Tin Bismuth vs. Gold), current rating per contact (0.5A vs. 1A), operating temperature range (-40°C ~ 85°C vs. -55°C ~ 105°C), and additional features (Flip Lock, Zero Insertion Force) require application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

HFW4R-1STAE1H1LF is the primary substitute for HFW4R-1STAE1LF. Both parts are manufactured by Amphenol ICC and share identical electrical and mechanical specifications. The HFW4R-1STAE1H1LF maintains active product status, ensuring long-term availability and supply chain continuity. Housing material composition differs (LCP, Halogen Free vs. PA6T, Nylon 6T, Glass Filled), but both materials meet UL94 V-0 flammability requirements and RoHS compliance. This substitute is suitable for direct replacement in existing designs without modification.

2005290040 (Molex Easy-On 200529) is a cross-manufacturer alternative meeting core mechanical and electrical compatibility criteria. Selection of this part requires application-specific evaluation due to the following differences:

• Current rating is 0.5A per contact versus 1A for the original part
• Operating temperature range is -40°C ~ 85°C versus -55°C ~ 105°C
• Contact finish is Tin Bismuth versus Gold
• Additional features include Flip Lock and Zero Insertion Force (ZIF)

The 2005290040 is suitable for applications where the reduced current capacity and narrower temperature range are acceptable, and where the additional locking and insertion force features provide functional benefits.

Frequently Asked Questions (FAQ)

Q: Can HFW4R-1STAE1H1LF be used as a direct replacement for HFW4R-1STAE1LF?

A: Yes. Both parts are manufactured by Amphenol ICC, share identical connector geometry (4 positions, 1.00mm pitch, right-angle surface mount), and meet equivalent electrical specifications (100V, 1A, -55°C ~ 105°C). The HFW4R-1STAE1H1LF is the active production equivalent and is suitable for direct substitution without design modification.

Q: What are the key differences between HFW4R-1STAE1H1LF and 2005290040?

A: The primary differences are: (1) Manufacturer – Amphenol ICC versus Molex; (2) Current rating – 1A versus 0.5A per contact; (3) Operating temperature – -55°C ~ 105°C versus -40°C ~ 85°C; (4) Contact finish – Gold versus Tin Bismuth; (5) Locking mechanism – Solder Retention only versus Flip Lock with Zero Insertion Force. These differences require application-level compatibility assessment.

Q: Is the 2005290040 suitable for high-temperature applications?

A: The 2005290040 operates to 85°C maximum, which is 20°C lower than the original HFW4R-1STAE1LF specification of 105°C. Applications requiring operation above 85°C must use HFW4R-1STAE1H1LF or the original part.

Q: Are all three parts RoHS compliant?

A: Yes. HFW4R-1STAE1LF and HFW4R-1STAE1H1LF are RoHS Compliant. The 2005290040 is ROHS3 Compliant. All three parts meet current RoHS requirements.

Q: What is the packaging format for each substitute?

A: HFW4R-1STAE1LF packaging is not specified. HFW4R-1STAE1H1LF is supplied in Tape & Reel (TR) format. The 2005290040 is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly processes.

Q: Can the 2005290040 be used in applications requiring 1A current capacity?

A: No. The 2005290040 is rated for 0.5A per contact, which is half the 1A rating of the original part. Applications requiring 1A current capacity must use HFW4R-1STAE1H1LF or the original HFW4R-1STAE1LF.
