Grayhill 62D15-02-P Rotary Encoder Optical 24PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62D15-02-P is an optical rotary encoder with 24 pulses per revolution (PPR), delivering quadrature (incremental) output in a vertical orientation. This Active product operates at 5V supply voltage with a 1/4" diameter flatted end actuator, detent mechanism, and integrated switch functionality. The encoder is mounted via PCB through-hole termination with PC pins and maintains 1 million cycle rotational life rating.

Substitute parts become necessary when addressing specific application requirements such as alternative pulse resolution, different supply voltage compatibility, or series-specific mechanical or electrical characteristics while maintaining core functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 62D15-02-P is determined by the following critical parameters:

Primary Substitution Criteria:

• Encoder Type: Optical
• Output Type: Quadrature (Incremental)
• Actuator Type: 1/4" Dia Flatted End
• Mounting Type: PCB, Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Rotational Life: 1M cycles minimum
• Compliance: ROHS3 Compliant, REACH Unaffected

Variable Parameters Allowing Substitution:

• Pulses per Revolution (24, 16, or 12 PPR)
• Voltage - Supply (5V or 3.3V)
• Series designation (62D, 62R, 62S, 62N, 62V)

The substitute parts listed maintain all primary criteria while permitting variation in pulse resolution and supply voltage to accommodate different application-specific resolution and power requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Same PPR, Same Voltage):

62R15-02-P and 62S15-M5-P are functionally equivalent to 62D15-02-P, both maintaining 24 PPR output at 5V supply. Selection among these three parts depends on series availability and inventory status. All three are Active products with ROHS3 compliance and REACH unaffected status.

Alternative Resolution Options (5V Supply):

62S22-M5-P provides 16 PPR output at 5V, suitable for applications requiring lower resolution than the primary 24 PPR specification. 62N30-P provides 12 PPR output at 5V for applications requiring the lowest resolution within this substitute group. Both maintain identical mechanical mounting, detent, and switch characteristics.

Alternative Voltage Option (24 PPR):

62V15-02-P maintains 24 PPR resolution but operates at 3.3V supply voltage instead of 5V. This part is suitable for low-voltage logic integration while preserving pulse resolution. All compliance certifications remain equivalent.

Compliance Verification:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and 1 million cycle rotational life rating. Moisture sensitivity level remains MSL 1 (Unlimited) across all options.

Frequently Asked Questions (FAQ)

Q: Can 62R15-02-P directly replace 62D15-02-P in existing designs?

A: Yes. Both parts share identical electrical specifications (24 PPR, 5V), mechanical mounting (PCB through-hole, vertical orientation), actuator type (1/4" flatted end), and functional features (detent, built-in switch). Series designation change does not affect compatibility.

Q: What is the functional difference between 24 PPR, 16 PPR, and 12 PPR encoders?

A: Pulses per revolution determines angular resolution. 24 PPR provides 15-degree increments per pulse, 16 PPR provides 22.5-degree increments, and 12 PPR provides 30-degree increments. Selection depends on application resolution requirements.

Q: Can 62V15-02-P operate in a 5V system designed for 62D15-02-P?

A: No. 62V15-02-P requires 3.3V supply voltage. Direct substitution into a 5V circuit will result in component damage. Voltage regulation or circuit redesign is required for compatibility.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All listed substitute parts are supplied in Bulk packaging with PC pin termination style, matching the original 62D15-02-P packaging specification.

Q: What inventory status applies to substitute parts?

A: 62R15-02-P: 637 units in stock; 62S15-M5-P: 1007 units in stock; 62S22-M5-P: 1309 units in stock; 62N30-P: 755 units in stock; 62V15-02-P: 729 units in stock. All are Active products.
