Key Parameters

Substitute Part Grouping Explanation

Substitution of the BM02B-LEHSS-A-TB(HF) is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 2-position header with male pins
• Pitch Specification: 0.071" (1.80mm) center-to-center spacing
• Electrical Ratings: 300V voltage rating and 3A current capacity
• Termination Method: Solder attachment
• Mounting Style: Surface mount, right angle orientation
• Material Compatibility: Polyamide (PA9T) housing with copper alloy tin-plated contacts
• Environmental Performance: Operating temperature range of -55°C to 105°C and MSL 1 rating

The SM02B-LEASS-TF meets all these critical parameters and qualifies as a direct functional equivalent. The primary distinction is product status: the substitute part is active and available, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The SM02B-LEASS-TF is the appropriate substitute for the obsolete BM02B-LEHSS-A-TB(HF). All critical electrical, mechanical, and environmental parameters are equivalent. The substitute part carries active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

Differences in housing color (natural versus white) and packaging format (bulk versus tape & reel) do not affect functional compatibility. The tape & reel packaging of the substitute part provides advantages for automated assembly processes and inventory management.

Frequently Asked Questions (FAQ)

Q: Can SM02B-LEASS-TF be used as a direct replacement for BM02B-LEHSS-A-TB(HF)?

A: Yes. Both connectors share identical electrical ratings (300V, 3A), mechanical configuration (2-position, 0.071" pitch, surface mount right angle), termination method (solder), and material specifications (PA9T housing, copper alloy tin-plated contacts). Functional compatibility is complete.

Q: What is the significance of the housing color difference?

A: Housing color (natural versus white) is a cosmetic distinction with no impact on electrical performance, mechanical fit, or environmental ratings. Selection between colors depends on application aesthetics or internal documentation standards only.

Q: Does the packaging format affect compatibility?

A: No. The original part is supplied in bulk packaging, while the substitute is supplied in tape & reel format. Both contain identical connector components. Tape & reel packaging is standard for high-volume manufacturing and automated placement equipment.

Q: Is ROHS3 compliance important for this substitution?

A: ROHS3 compliance of the substitute part ensures adherence to current environmental and hazardous substance regulations. This is advantageous for products destined for markets with regulatory requirements. The original part's compliance status is not specified in available documentation.

Q: Are there any temperature or voltage derating considerations?

A: No. Both parts operate across the identical temperature range (-55°C to 105°C) and voltage rating (300V). Current capacity is 3A for both connectors. No derating or operational adjustments are required.
