• Number of Positions: 2
• Number of Rows: 1
• Mounting Type: Surface Mount
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Detent Lock
• Operating Temperature: -25°C ~ 85°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The M30-6000246R is an active product with improved availability (2609 pcs in stock versus 757 pcs for the obsolete part) and maintains functional and electrical compatibility within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The M30-6000246R is the direct active equivalent for the obsolete M30-3010246R. Selection of the substitute part is based on:

Product Status: The M30-6000246R maintains active production status with significantly higher inventory availability, ensuring supply chain continuity for new designs and production runs.

Compliance & Certifications: Both parts maintain identical compliance profiles including ROHS3 compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental requirements are met.

Electrical Performance: The M30-6000246R provides enhanced electrical specifications with 150V voltage rating compared to 100V for the obsolete part, while maintaining the same 1A current rating and operating temperature range of -25°C to 85°C.

Physical Compatibility: Minor dimensional variations exist (insulation height 4.80mm versus 4.90mm, contact shape square versus rectangular), which remain within acceptable tolerances for the M30 series connector family and do not affect functional interchangeability in standard board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

Q: Can M30-6000246R directly replace M30-3010246R in existing designs?

A: Yes. Both parts share identical pitch (1.25mm), position count (2), mounting type (surface mount), termination method (solder), and shrouding configuration (4-wall). The substitute maintains the same operating temperature range and compliance certifications.

Q: What are the differences between these parts?

A: The M30-6000246R features a square contact shape versus rectangular, uses brass instead of phosphor bronze contact material, and includes PA6T insulation material instead of PA9T. The substitute also provides 150V voltage rating versus 100V and includes board guide features. Insulation height differs by 0.1mm (4.80mm versus 4.90mm).

Q: Why is the voltage rating higher on the substitute?

A: The M30-6000246R represents an improved design iteration within the M30 series. The enhanced 150V rating provides additional design margin without affecting compatibility with applications rated for 100V operation.

Q: What packaging options are available?

A: The M30-3010246R was supplied in bulk packaging. The M30-6000246R is available in Tape & Reel (TR) packaging, which is standard for high-volume surface mount production.

Q: Are there any PCB layout considerations when switching to the substitute?

A: The 0.1mm difference in insulation height (4.90mm to 4.80mm) is negligible for standard PCB design. The square contact geometry of the M30-6000246R maintains compatibility with existing footprints designed for the M30 series 1.25mm pitch header.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, carry UL94 V-0 flammability rating, and have MSL 1 (unlimited) moisture sensitivity level, ensuring identical regulatory and environmental compliance.
