Key Parameters

Substitute Part Grouping Explanation

The MDF76LBRW-30S-1H(98) has been identified with one active equivalent: MDF76LBRW-30S-1H(55). This substitution is valid based on the following critical parameters that remain constant across both parts:

• Base product number: MDF76 (same connector family)
• Number of positions: 30
• Pitch - mating: 0.039" (1.00mm)
• Mounting type: Board Cutout, Surface Mount, Right Angle
• Termination method: Solder
• Fastening type: Push-Pull
• Voltage rating: 200VAC
• Operating temperature range: -40°C ~ 85°C

The primary distinction between these parts is the product status transition from obsolete to active production, along with updated compliance certifications and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MDF76LBRW-30S-1H(55) is the designated active equivalent for the obsolete MDF76LBRW-30S-1H(98). Selection of this substitute is supported by:

• Identical connector family designation (MDF76 base product number)
• Matching electrical specifications: 30 positions, 0.039" (1.00mm) pitch, 200VAC rating, -40°C ~ 85°C operating range
• Identical mechanical interface: Board cutout, surface mount, right angle configuration with push-pull fastening
• Active production status ensuring availability and supply chain continuity
• RoHS compliance certification for the substitute part, meeting current regulatory requirements
• MSL rating of 1 (Unlimited) for the substitute part, indicating minimal moisture sensitivity constraints

For applications requiring the obsolete MDF76LBRW-30S-1H(98), the MDF76LBRW-30S-1H(55) provides direct functional compatibility with updated compliance and availability advantages.

Frequently Asked Questions (FAQ)

Q: Can MDF76LBRW-30S-1H(55) directly replace MDF76LBRW-30S-1H(98) in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications: 30 positions, 0.039" (1.00mm) pitch, 200VAC rating, -40°C ~ 85°C operating temperature, board cutout surface mount right angle configuration, and push-pull fastening. The substitute is an active production part with current compliance certifications.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance. MDF76LBRW-30S-1H(98) is obsolete, while MDF76LBRW-30S-1H(55) is in active production. The substitute includes RoHS compliance certification and is supplied in Tape & Reel packaging format.

Q: Are there any compatibility concerns with the packaging format?

A: The substitute part is supplied in Tape & Reel (TR) packaging, which is standard for surface mount components. This format is compatible with automated assembly processes. If manual handling or alternative packaging is required, contact the manufacturer directly.

Q: What is the MSL rating difference, and does it affect substitution?

A: The obsolete part lists MSL as Not Applicable, while the substitute specifies MSL 1 (Unlimited). MSL 1 indicates minimal moisture sensitivity, which is favorable for storage and handling. This does not prevent substitution; it represents an improvement in handling flexibility.

Q: Is the gold contact finish on the substitute part significant?

A: The substitute specifies gold contact finish on mating surfaces with 12.0µin (0.30µm) thickness. This is a standard finish for Hirose rectangular connectors and ensures reliable electrical contact. The contact finish does not affect mechanical compatibility or electrical performance within the specified voltage and temperature ratings.
